linspace(1,100,1000) would contain non-integer values, which cell would not be able to use a dimension sizes to construct a 1000-dimensional cell array.

str = sprintf('%04d\n',0:1000)

No. In MATLAB, numbers automatically drop leading 0's when displayed.
What is possible is to create a cell array of strings from '0000' to '1000'.
cellstr(num2str(0:1000).', '%04d')
Note: the .' is required there; without it the strings would come out wrong.

There is also the undocumented
sprintfc('%04d', 0:1000)
Also since R2016b, there has also been
compose('%04d', 0:1000)
